Question

What are all the forces a person is subjected to in a G force simulator?

Details

In a G force centrifuge a test pilot is exposed to high G forces, however recently I've been learning about centripetal force and the coriolis force (pseudo force). I became a little confused when considering a G force centrifuge as prior to considering these forces properly I presumed the only force acting on the test pilot was the centripetal force, thats why in videos of them you see a little G force counter telling you how many g's the pilot was dealing with before he/she passed out.

The images show a representation of a pilot inside a G force centrifuge. The pilot is denoted by the bronze/gold geometry, the circular end representing the pilots head and the square end representing the pilots feet, the platform the pilot is attached to represents his feet.

Now as I understand it, when the centrifuges rpm increases the pilots blood begins to pool towards his feet which is the centripetal force, I understand that and know how to approximately calculate it

F = Mass (Velocity^2) / radius

However there is also the force of earths gravity which doesn't increase or decrease as the centrifuge spins, but my main question is, isn't there another force accelerating the pilot into his seat and that force is dependant on the rpm, even when the rpm has levelled out and is constant, that force is still there pinning our pilot into his seat. Is that the case? Or as long as the pilot survives the acceleration he is no longer pinned to his seat and the only force he now feels is the centripetal force?

Is the force pinning the pilot to his seat the coreolis effect and if so is the velocity component of the coreolis equation the speed at which the pilot is traveling along the circumference of the circular path?
